Turn on <em>bounce keys</em> to ignore key presses that are rapidly repeated. For example, if you have hand tremors which cause you to press a key multiple times when you only want to press it once, you should turn on bounce keys.

Use the <gui>Acceptance delay</gui> slider to change how long bounce keys waits before it registers another key press after you pressed the key for the first time. Select <gui>Beep when a key is rejected</gui> if you want the computer to make a sound each time it ignores a key press because it happened too soon after the previous key press.
